These design documents are historical. While they often provide insight into design choices made, they are not maintained after initial implementation and in most cases will not reflect the current functionality. They may be very useful to understand why features are implemented the way they are, what kind of design goals they were optimized for, alternatives that were rejected etc.

Please consult the documentation for the project for current status.
